Failure to observe the illuminated text messag-es can lead to the vehicle being damaged. The areas to the front and rear of the vehicle that are scanned by ultrasound sensors are shown on the screen of the factory-fitted radio or navigation system. The positions of potential obstacles are displayed relative to the vehicle &.
The areas to the front (only with ParkPilot front and rear) and rear of the vehicle are fully scanned by the ultrasound sensors.
Acoustic signals and screen
Acoustic signals are given when the vehicle ap-proaches an obstacle located in the range of the ultrasound sensors. An intermittent signal tone is given if a sufficiently short distance between the vehicle and an obstacle is detected. The shorter the distance, the shorter the intervals. The signal tone will sound continuously if the obstacle is very close.
If you continue to drive the vehide closer to the ob-sta de despite the continuous signal tone, the sys-tem will no longer be able to measure the distance.
With some vehicle equipment levels the scanned areas may be displayed as several segments in a display. The closer the vehicle drives lowards an obstacle, the closer the segment will move to the vehicle in the display. The collision area has been reached when the penultimate segment is dis-played, if not before. Do not drive onl .,..

Adaptive cruise control combines cruise
control and distance control.
The Adaptive Cruise Control (ACC) can help to maintain a speed set by the The adap-tive cruise control (ACC) can also maintain a set time interval to a vehicle travelling ahead. Two fac-tory-fitted versions of the system are available: .,

• System version 1 functions at speeds of 30-160 km/h (20 mph -100 mph).
• System version 2 functions at speeds of 30-210 km/h (20 m ph-130 m ph).
In vehicles with a dual clutch gearbox DSG®, the adaptive cruise control (ACC) can brake the vehi-cle until it comes to a complete standstill behind a vehicle in front that is stopping.
Driver prompt to take over control
There are system-specific limits on the adaptive cruise control (ACC) when driving. This means that the driver may have to control the speed and dis-tance between the vehicle and other vehicles in certain circumstances.
The driver is told to take control of the vehicle via a message on the instrument cluster display prompts a braking intervention, and a signal tone =<>page 300.

A WARNING
The intelligent technology used in the adap-tive cruise control (ACC) cannot overcome the laws of physics, and functions only within the limits of the system. Careless or uninten-tional use of the adaptive cruise control (ACC) can cause accidents and lead to seri-ous injury. The system Is not a substitute for the full concentration of the driver.
• Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and traffic conditions.
• Do not use the adaptive cruise control (ACC) in poor visibility, on steep or winding roads, or on slippery road surfaces e.g. on snow, ice, wet roads, loose chippings or floo-ded roads.
A WARNING (Continued)
• Never use the adaptive cruise control (ACC) off-road or on unsurfaced roads. The adaptive cruise control (ACC) is designed for use on surfaced roads only.
• The adaptive cruise control (ACC) does not react to stationary obstacles, e.g. the tail end of a traffic jam, a vehicle that has broken down, or vehicles waiting at traffic lights.
• The adaptive cruise control (ACC) does not react to persons, animals or vehicles crossing or approaching in the same lane.
• If the adaptive cruise control (ACC) speed reduction is insufficient, you should brake the vehicle by depressing the foot brake.
• Brake the vehicle by depressing the brake if the vehicle rolls inadvertently on after the driver has been prompted to take control of the vehicle.
• If the instrument cluster display indicates that the driver should take control of the vehi-cle, you have to regulate the distance your-self.
• The driver must be prepared to take con-trol of the vehicle (by accelerating or braking) at all times.
CD
Switch off the adaptive cruise control (ACC) if you suspect that the radar sensor has been damaged. This can help to prevent secondary damage. Have the radar sensor realigned.
• Repair work on the radar sensor will require special knowledge and tools. Volkswagen rec-ommends using a Volkswagen dealership for this purpose.
m If the adaptive cruise control (ACC) does not L!J function as described in this chapter, do not use it, and have the system checked by a qualified workshop. Volkswagen recommends using a Voikswagen dealership for this purpose.
m The maximum vehicle speed when the adap-L!J live cruise control (ACC) is active is limited to either 160 km/h (1 00 m ph) or 210 km/h (130 m ph). depending on the system version.
m If the adaptive cruise control (ACC) is active, L!J unfamiliar noises may be heard during the automatic braking procedure. These are caused by the braking system. Driver assist systems I 299

Several warning and indicator lamps will light up briefly as a functional check when the ignition is switched on. They will go out after a few seconds.
A WARNING
Failure to observe the warning lamps and text messages could lead to accidents and seri-ous Injuries.

A radar sensor is fitted to the front bumper to moni-tor the traffic situation 240 @.Vehicles trav-elling ahead can thus be detected up to a distance of approximately 120 m.
The efficacy of the radar sensor can be impaired by contamination such as slush or snow. or by en-vironmental conditions such as heavy rain or spray. This means that the adaptive cruise control (ACC) also will not work. The instrument cluster display shows the message ACC: No distance con-trol ! . Clean the radar sensors as required
The adaptive cruise control (ACC) will automatical-ly be available again as soon as the radar sensors are no longer impaired. The message on the in-strument cluster display goes out. and the adaptive cruise control (ACC) can be reactivated.
A WARNING (Continued)
• Never ignore any illuminated warning lamps or text messages.
CD
Failure to observe illuminated indicator lamps and text messages can lead to your vehicle be-Ing damaged.
m When the adaptive cruise control (ACC) is L!..J switched on, some system-related displays on the instrument cluster can be overwritlen by other functions, e.g. incoming telephone calls. Strong reflected radiation of the radar signal, e.g. in multi-storey car parks, can impair the function of the adaptive cruise control (ACC).
The area in front of and around the radar sensor ® must not be covered by objects such as stick-ers, auxiliary headlights, face plates for number plates or the like, as this can impair the function of the adaptive cruise control (ACC).
Any structural modifications to the vehicle, e.g. lowering the vehicle or making alterations to the front end trim, can impair the function of the adap-tive cruise control (ACC). Structural modifications should therefore always be carried out by a quali-fied workshop. Volkswagen recommends using a Volkswagen dealership for this purpose.
Incorrectly performed repairs to the front end of the vehicle can alter the position of the radar sensor and therefore impair the function of the adaptive cruise control (ACC). Repair work should therefore only be carried out by a qualified workshop. Volks-wagen recommends using a Volkswagen dealer-ship for this purpose.
CD
Switch off the adaptive cruise control (ACC) If you suspect that the radar sensor has been damaged or is incorrectly positioned. This can help to prevent secondary damage. Have the radar sensor realigned.
• The radar sensor could be moved if it is hit, for example in parking manoeuvres. Readjust-Ing the sensor could impair the performance of the system or cause it to be switched off. 11>

The adaptive cruise control (ACC) has physical and system-related limits. As a result, certain adaptive cruise control (ACC) system reactions may occur, from the driver's perspective, unexpect-edly or with some delay. You should therefore al-ways be prepared to take full control of the vehicle if necessary.
The following traffic situations, for example, require particular vigilance:
Deceleration to standstill, only vehicles with dual clutch gearbox DSG®
If a vehicle travelling ahead brakes to a standstill, the adaptive cruise control (ACC) will also brake your vehicle to a standstill. The vehicle is then held stationary by the brakes.
Stationary phase, only vehicles with dual clutch gearbox DSG®
After the adaptive cruise control (ACC) has slowed down the vehicle to standstill, the vehicle is kept stationary for a short period of time. During the sta-tionary phase the driver is prompted to depress the brake pedal 300. If the brake pedal is de-pressed, the adaptive cruise control (ACC) is switched off. If the brake pedal is not depressed within the stationary phase, the adaptive cruise control (ACC) is switched off automatically.
Overtaking
If the tu m signal is activated when starting an over-taking manoeuvre, the adaptive cruise control (ACC) accelerates the vehicle automatically and thus reduces the distance to the vehicle in front.
If you move your vehicle into the overtaking lane and there is no vehicle ahead of you, the adaptive cruise control (ACC) will automatically increase the speed to your set level and maintain it. .,..
Driver assist systems I 305

Acceleration can be stopped at any time by de-pressing the brake pedal or pressing the(@ or @ button on the multifunction steering wheel 302.
When driving through bends
While driving through bends, the radar sensor may sometimes lose the vehicle travelling ahead or may react to a vehicle in the next lane 242 !Al. In such situations, the vehicle might decelerate unnecessarily or not react to the vehicle in front. In this case the driver must override the adaptive cruise control (ACC) by depressing the accelerator, or interrupt the braking procedure by depressing the brake pedal or pressing or @ button on the multifunction steering wheel 302.
Driving in tunnels
The radar sensor function may be restricted in tun-nels. Switch off the adaptive cruise control (ACC) in tunnels.
Narrow vehicles and a zig-zag traffic situation
Narrow vehicles and vehicles travelling slightly to the left or right of your vehicle will only be recog-nised by the radar sensor once they have entered the radar range 242@ This applies in par-ticular to narrow vehicles such as motorbikes. If re-quired, brake the vehicle yourself.
Vehicles with special load or special equipment
Any load or accessories on other vehicles that pro-trude from the side, rear or over the roof of the ve-hicle may not be detected by the adaptive cruise control (ACC) .
Switch off the adaptive cruise control (ACC) when the vehicle ahead has special load or special equipment, or while overtaking vehicles of this kind. If required. brake the vehicle yourself.
When other vehicles change lanes
Vehicles that are very close when they move into your lane can only be detected by the radar sen-sors when they have moved into the sensor range. This means that the adaptive cruise control (ACC) may have a delayed reaction =>Fig. 243@]. If re-quired, brake the vehicle yourself.
Stationary vehicles
The adaptive cruise control (ACC) does not detect stationary objects during a journey, e.g. stationary traffic or a vehicle that has broken down.
306 I While driving
If a stationary vehicle is hidden behind a vehicle that has been detected by the adaptive cruise con-trol (ACC) and this vehicle turns off the road or changes lane, the adaptive cruise control (ACC) will not be able to react to the stationary vehicle 243 [Q]. If required, brake the vehicle your-self.
Oncoming vehicles and vehicles crossing your path
The adaptive cruise control (ACC) does not react to approaching vehicles or vehicles crossing your path.
Metal objects
Metal objects, such as tracks in the road or metal plates used in roadworks, can confuse the radar sensor and cause incorrect reactions from the adaptive cruise control (ACC) .
Possible radar sensor function impairments
The adaptive cruise control (ACC) will switch off temporarily if the radar sensor function is impaired, e.g. due to heavy rain, spray, snow, ice or mud. A corresponding message will appear on the instru-ment cluster display. Clean the radar sensors as required.
The adaptive cruise control (ACC) will automatical-ly be available again as soon as the radar sensors are no longer impaired. The message on the in-strument cluster display goes out, and the adaptive cruise control (ACC) can be reactivated.
Strong reflected radiation of the radar signal, e.g. in multi-storey car parks, can impair the function of the radar sensor.
Towing a trailer
The adaptive cruise control (ACC) operates with reduced dynamics when the vehicle is towing a trailer.
Overheated brakes
If the brakes overheat, e.g. following heavy braking or when driving down steep inclines for long peri-ods, the adaptive cruise control (ACC) may be de-activated temporarily. A corresponding message will appear on the instrument cluster display. lt is then not possible to activate the adaptive cruise control (ACC).
As soon as the temperature of the brakes has de-creased sufficiently, the adaptive cruise control (ACC) can be activated again. The message on the instrument cluster display goes out. If the mes-sage ACC not ava i 1 able does not go out for a long time, there is a fault. Go to a qualified work-shop. Volkswagen recommends using a Volkswa-gen dealership for this purpose.
